EMC Power Entry Module Insertion Loss (S21 Magnitude) Model calculator computes Insertion Loss in dB using the defined engineering formula and the input values provided. Insertion Loss is expressed in dB. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Frequency = 100000
  • Filter Resonant Frequency = 1000000
  • Series Damping Resistance = 0.5
  • Characteristic Impedance = 50

Expected Result:

  • Insertion Loss = 0.087295000268095

Engineering Interpretation:

Under the given input conditions, the calculated result is: Insertion Loss = 0.087295000268095 dB.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.

Formula / Method

insertion loss = -20 * log(sqrt((1 - pow(frequency / filter resonant frequency, 2)) * (1 - pow(frequency / filter resonant frequency, 2)) + pow(frequency / filter resonant frequency * (series damping resistance / (2 * characteristic impedance)), 2))) / log(10)

Insertion Loss.
